“…The results of investigations at all structural levels allowed carrying also evaluation of such quite considerable indices of mechanical properties as indices of crack resistance of alloyed layers of surfaces being treated under different investigated modes. Analysis of crack resistance indices was carried out considering distribution of dislocation density based on evaluation of level of local internal stresses according to dependence [12]…”

The results of investigations of structural-phase conditions in surface layers of structural steel 38KhN3MFA and their changes under different modes of strengthening by laser and laser-plasma alloying are given. Experimental investigations were used as a basis for analytical evaluation of differential input of all structures being formed in strengthening and their parameters (chemical composition, grain and subgrain structures, dislocation density, volume fraction of phase precipitates etc.) in change of strength characteristics of alloyed layers, conditions of crack formation promoted by formation of local internal stress concentrators, i.e. zones of nucleation and propagation of cracks, as well as mechanisms for relaxation of such type of stresses. 12 Ref., 6 Figures.

“…In addition to mentioned above analytical estimations of contribution of structures in change of strength and fracture toughness of the metal, effect of some structural factors on such process as crack formation and providing of crack resistance of examined welded joints operating under complex conditions of cyclic load was also determined. Estimations of the local internal stresses τ l.int in specific examined zones, considering dislocation density in typical structural constituents, were carried out using dependence, calculation of which is given in [15]:…”

“…To assess the role of technological modes used in friction stir welding (FSW), in the change of welded material properties, namely strength, ductility and crack resistance characteristics [2][3][4][5][6], it appears appropriate to compare the dependencies of welding modes ↔ joint properties with similar interconnections studied (and in sufficient detail) for the regularly used processes of aluminium alloy welding, to which TIG welding belongs.…”

An essential difference in formation of structural-phase state at application of different welding conditions-friction stir welding compared to argon-arc welding-is considered in the case of welded joints of complex aluminium-lithium alloys. The urgency of comprehensive experimental-analytical assessment of interrelation of welded joint structure and properties is also shown. Assessments of specific contribution of structural-phase state (chemical composition, phase dimensions, grain, subgrain and dislocation structure) into the change of the main service properties of welded joints made by argon-arc welding and friction stir welding are considered, as well as the influence of welded joint structural state on the nature of distribution, level of growing internal stresses and their relaxation mechanisms under specific welding conditions. 10 Ref., 5 Figures.
